Professional Applications & Engineering Value

This M10 shoulder screw is engineered to address critical alignment and load-bearing challenges in precision machinery, automation systems, and rotating assemblies. The 18-8 Stainless Steel construction provides excellent corrosion resistance, ideal for humid or chemically exposed environments. Its 20mm shoulder with controlled tolerances acts as a precise pivot or spacer, reducing friction and preventing misalignment in bearings, linkages, and gear mechanisms. The hex socket head with knurling ensures secure tool engagement, even in confined spaces, while the Class 5g6g metric thread maintains consistent clamping force. By combining high tensile and shear strength with reliable thread integrity, this shoulder screw minimizes downtime and enhances the longevity of industrial equipment.

Specification Summary & Compliance

The screw features a M10x1.5mm coarse thread with Class 5g6g tolerance per metric standards, ensuring precise fit and interchangeability. Shoulder diameter tolerance is -0.04 to -0.01 mm, and shoulder length tolerance is 0 to 0.25 mm for accurate assembly. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming it is free of restricted hazardous substances. Manufactured to deliver consistent performance, it meets industry demands for reliability in mechanical applications.
